To'all'whom itmag concern:

Be it known that I, NORMAN ELLIOTT, a

citizen of the United States, 'residing at Cleveland in the county of uyahoga and State of hio, have invented a certain new and useful Improvement in Lamps for Veblcles, of which the following is a .full, clear and exact description, reference being had to the accompanying drawings. 7

This invention relates to' lamps for vehicles (such as automobiles) and has for its which will be capable of operating efiicientlynot only as a tail lamp, but as a warning lamp to ind1- cate to others the stopping of the vehicle or the checking of the speed thereof, as by the application of the brakes thereto. A further and more limited obj ect of the invention is to improve and simphfy the construction and operation of lampsof this character.

I accomplish; these objects in and through a lamp such as shown. in the accompanying drawing, wherein Figure 1 represents a rear elevation thereof and Fig. 2 a central vertical sectional" view corresponding i substan- .tially to the line 2-2 of Fig. 2, both bulbs and their sockets being shown in elevation.

- Describing the parts by reference characters, 1 denotes a sheet metal casing, generally hemispherical in shape and having its open end provided with an angular peripheral flange 2 forming a seat for the lens or to its .upper sect1on, and has formed theresection.

The upper portion of thepane has molded thereon or otherwise applied thereto a warning signal, 'shown as the. word Stop the I zontal partition 8 extending from the rear letters of which are ofacolor which, when 'the upper section of the pane is illuminated,

will contrast with the color of the said upper section. ,For this. purpose the glass of the upper'section may be clear or dark and the glgss'corr'esponding to-the letters may be re The pane 3 may be secured upon its seat within the flange 2by means of a split channel-shaped locking rlng 5 having-lugs 6 connected by a bolt or screw '7. t

The casing 1 is divided by a central horior open end thereoi to the closed or front end. Mounted in and projecting'upwardly ane 3. s The said lens or pane is preferably p ain as.

fromlsaid partition is a socket 9 for the neck of agbulb 10. Also mounted in and projectmg downwardly from said partition is a ing 1 and the partition 8 there is located a reflector 13, sa1d reflector cooperating with the bulb 10 to assist in illuminating the warning signal on the pane 3.

The lower portion of the pane is shown as provided wlth a convex lens section 4, in

order to provide with the bulb 12 an efficient tail light. Where such convex lens is employed, the portion of the pane below the .part1t1on 8 and surrounding the said lens may be opaque.

Below the bulb 12, the casing is provided with a slot 14 which is covered by a pane of socket 1 1 for the neck of a bulb 12. j Within,

the upper compartment provided by the casof the service brakes) to illuminate the v warning or stop signal as the movement of the vehicle is checked. Any of the stand. ard or' known methods of controlling the cir- .cuit including said bulb may be employedv for this purpose. The bulb 12 is intended to be operated in the usual manner for taillight'purposes, the lamp being-placed above and in front of the license plate so that the white light projects through the slot .14 and pane 15 mayilluminate sald plate.

The front or closed end-of the casing 1 is flattened, as indicated at 1, providing a convenient means for attachment of a bracket 16.

the lamp to By reason (if the construction and arrangement of parts shown and described herein, I have produced a lamp which is capable of operating in a most satisfactory manner for the double'pu ose of: auto matically illuminating or disp aying a warning signal as wellas operating as an efiicient tail lamp. Furthermore, I have accomplished this result in and through a construction and arrangement of parts whioh result production.

By making the lens 4 a unitary part of the pane .3, a single clamping device sufiices for the. cover for both the warning signal compartment and the taillight compartment of the lamp. The partition 8 preferably in simplicity of construction and economy of of the casing, said pane having a fiat or plane portion covering one of said compartments and abutting against said partition and having on such fiat or plane portion a Warning signal on one side of the partition and on the opposite side a lens for a tail llght, and a bulb for each compartment.

In testimony whereof, I hereunto affix my signature. I
